Building a web application begins by outlining user roles, primary use cases, and the data structure. A robust MVP concentrates on essential paths, intuitive navigation, and consistent UI elements, enabling the product to launch rapidly without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability take priority: performance budgets, caching, strong authentication, and tidy API contracts. With solid monitoring, CI/CD, and well-considered architecture, teams can iterate more quickly while maintaining a stable codebase as features and user demand expand.
